 <h1>XSCHEM HISTORY</h1>


  <h3 style="text-align:left; margin-left:3%;">
   <ul>
    <li>Started in 1998 as a hobby home project when i was working at STM.</li>
    <li>First versions were developed on solaris sparc, then on linux.</li>
    <li>Subversion local repository in 2007.</li>
    <li><a href="https://sourceforge.net/projects/xschem">Sourceforge</a> svn repository in December 2016.</li>
    <li>Cairo Text option for fonts added in 2017.</li>
    <li><a href="http://repo.hu/projects/xschem">XSCHEM</a> joins <a href="http://repo.hu/projects/coraleda">CoralEDA</a> on <a href="http://repo.hu">repo.hu</a> on October 2018. 
        Both CoralEDA and Sourceforge repos are maintained.</li>
    <li>Development boost happened in 2018 to present:</li>
     <ol>
       <li>More graphic primitives (polygons, arcs, circles).</li>
       <li>Automatic <a href="http://repo.hu/projects/scconfig">'configure'</a> configuration.</li>
       <li>standard location of installed files / docs / rcfiles.</li>
       <li>Lot of improvements and bug fixes.</li>
     </ol>
    <li>Some small startups start using Xschem in 2019, getting feedbacks, bug reports and requests for improvements.</li>
    <li>Succesfully simulated designs (even complete systems) on 
     <a href="https://sourceforge.net/projects/ngspice">NGSPICE</a>, 
     <a href="https://xyce.sandia.gov">Xyce</a>, HSPICE, 
     <a href="ftp://icarus.com/pub/eda/verilog/v10">Icarus Verilog</a>, ModelSim, 
     <a href="https://github.com/ghdl/ghdl">GHDL</a>. Generic interface to simulation engines added in 2019.
    <li>Bindings for <a href="https://sourceforge.net/projects/gtkwave/">Gtkwave</a>,  <a href="http://gaw.tuxfamily.org/">Gaw</a> (Gwave improvement)  for waveforms in 2019.</li>
    <li>Adding bindings to other simulators (free/proprietary) and viewers is extremely simple (edit simrc file)</li>
    
   </ul>
